Product Details

Diamonds are a girl’s best friend! Stimulate student interest by growing 15 colorful “jewels” in your laboratory! In this hands-on activity, students will grow crystals of alum, chrome alum, copper sulfate and nickel sulfate—each with its own distinct color and shape. Each crystal is grown from a single seed crystal in a supersaturated solution. Watch students take ownership of their crystal and nurture it as it grows over a period of several weeks. This activity is a great way to introduce the concepts of saturation, supersaturation and crystal structure. Includes thread, index cards, instructions and enough chemical starting material to grow three of each crystal mentioned, for a total of 15 crystals.

Complete for 30 students working in pairs. Fifteen glass jars for growing crystals are required and available separately.

Performance Expectations

MS-PS1-4: Develop a model that predicts and describes changes in particle motion, temperature, and state of a pure substance when thermal energy is added or removed.
MS-PS1-2: Analyze and interpret data on the properties of substances before and after the substances interact to determine if a chemical reaction has occurred.
MS-PS1-6: Undertake a design project to construct, test, and modify a device that either releases or absorbs thermal energy by chemical processes.
MS-ETS1-3: Analyze data from tests to determine similarities and differences among several design solutions to identify the best characteristics of each that can be combined into a new solution to better meet the criteria for success.
HS-PS1-5: Apply scientific principles and evidence to provide an explanation about the effects of changing the temperature or concentration of the reacting particles on the rate at which a reaction occurs.
